4.13 HELICAL INVOLUTE INTERPOLATION (G02.2,G03.3)
This interpolation function applies involute Interpolation to two axes
and directs movement for up to four other axes at the same time. This
function is similar to the helical function used in circular interpolation.
Format
Explanation
- Commanded axes
Addresses α, β, γ, and δ must indicate axes other than Yp and Zp. Other
addresses must be the same as those used in the conventional involute
interpolation.
- Tool offset
Cutter compensation is only applied to involute curves.
- Linear axis and rotation axis
This function can be used for involute interpolation for a linear axis and
rotation axis.
